I vaguely remember reading something that said only OS&C ID'd players could buy passengers from the OS&C bases, I could be completely wrong on that one however.
It might be worth asking for evacuees as a special commodity, or even as an event depending on how you want to swing it. Refugees might be tough to work with as Tomioka, quite ironically, has a buy point for them from Leeds with no connection to any other Kusari planet other than Miura. If you want something a bit quicker there's always passengers_ga which are sold primarily on prisons, however the price would be a rather unappealing 1202 per unit due to Fuchu's proximity to New Tokyo.
